Callbacks on callouts do not work

Bug Issue #97 The (registerHelper or listen) do not work as intended for onClose/'close' and onShow/'show' for callouts.
If I use the invokeCallback - then the hopscotch.listen('show', 'myFuncShow') doesn't get triggered. Whereas the hopscotch.registerHelper('myFuncShow' function(){ console.log('Now showing); }); gets triggered properly.

Is hopscotch.listen only meant for tours?

I understand what you're saying, but if hopscotch.listen is meant only for tour-level and tours then we should document it (explicitly) just to be clear. (Just a suggestion) :-)
